-Be-it known that I, LOUIS BROWN, of New York, in the county of New;York and State of New York, a citizen of the United States, haveinvented a newandyuse'ful Improvement in Paints, of which the followingis a, full, clear,

and exact description;

In the-process of distilling zincthere is deposited in the pipes ortubes leading from the retortsa zinc powder or dust of exceedingfineness, which is not zinc white or an oxide of zinc, and which I naniesublimed zinc) in contradistinction to'flowcrs of zinc, zincwhite, orzinc in any other form; This dust is sometimes known as zinc-bluepowder,

or zincgdust/ and it has never so far as I .am aware been used in themanufacture of paint, After being deposited in the'condcnsertubesconnected with the retorts', it is re charged in the retorts and comesout in me-. tallic form at the next heat. I have discovered that paintscontaining this powder have a number of advantages over othermetallicpaints or paints of that character, and especially that theyhave much more body than any 9f either where of other paints two arealways necessary.

In making the paint, I vary the proportions of the zinc powder or dustto the remainder of the ingredients, according to the use for which itis intended, and I may use it in paints as a substitute for white leador zinc-white or zinc inany other form as now used; or it may lee-usedin combination with either of these pigments or bases.

To makeadrab paintfor vessels, 1 usefour parts of whiting, eight partsofthis zinc powder or dust, and :four parts of white lead.

The whiting, powder, and lead are intimately mixed and ground togetherand incorporated with suitable oil, turpentinaand-dricr-in the. ordinaryway.

of red and black ocher'.

A fine, olive green is made by using four parts of whiting, eight partsofthe zinc powder or dust, and four parts of red ocher. These areintimately mixed lay-grinding and incorporated with a proper vehicle anddrier in the ordinary wa A brown color, suitable for iron-work, isproduced by using eight parts of whiting, four parts of zinc powder ordust, and four parts islike that The process of makingthis pain ,of theothers: It'will also be obs rved that the above-men -tioned solidingredients of the paints-such as white lead,whiting, red ocher,blackocher are all substances which unite similarly with the vehicle, and areaspaint bodies the substantial equivalents of each other, except as theyaffect .the color of the paint, and they may be used indiflerently asauxiliary bodies to the zinc sublimate, the choice of the workman amongthem or other known constituents of the paint being governed by thecolor de;

sired. These proportions may be varicd'for difl'erenthindsof work and toobtain different shades.

I do not confine myself to the proportions herein indicated; neither'doI confine myself to the proportions of zinc powder or dust used {inmaking the paint, but would state that as a general rule from one-sixth(t) to twothirds ()of the base of the paint may be of this zinc powderor dust.

lhe advantages of the use .of this powder in paints havealready beenstated. l

-Having thus, fully described my invention,

I claim and desire to secure by Letters Patent of the United States-'Apaint made of sublimated-zinc powder, of

the character herein specified, combined with whiting or other suitablecoloring or filling matter and a vehicle. 7 V v p [Louis snows: Inpresence of- J 01m A. RoEBUcK,
